It conditionally injects that annotation into outgoing media messages. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-21T23:03:29.700Z - **Finished:** 2026-08-21T23:04:43.549Z - **Download time:** 758 ms - **Static scan time:** 8707 ms - **AI review time:** 64382 ms - **Total time:** 73849 ms ## Security analysis ### Published attack-surface review - **Summary:** Runtime message construction contains concealed brand constants and a newsletter media annotation. It conditionally injects that annotation into outgoing media messages. - **Trigger:** A consumer calls the package's media-message preparation path with the matching media options. - **Impact:** User-created media messages can carry undisclosed third-party newsletter branding or attribution. - **Evidence paths:** lib/Utils/messages.js, lib/Defaults/index.js, package.json, engine-requirements.js - **Review source:** ai\_review - **Reviewed:** 2026-08-21T23:04:43.549Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated insertion of branded newsletter metadata into outgoing media - **Attack narrative:** On import, the obfuscated message module initializes concealed newsletter brand values protected by an integrity hash. During media-message construction it builds a newsletter annotation and conditionally assigns it into the outgoing message object. This causes an unrelated package to alter users' WhatsApp media payloads with undisclosed third-party branding; the value concealment makes the behavior difficult for consumers to audit. - **Rationale:** The benign engine check does not explain the obfuscated runtime mutation. Concealed third-party branding injected into user messages is concrete, non-consensual payload manipulation. - **Files touched:** lib/Utils/messages.js ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** lib/Utils/messages.js is deliberately obfuscated and initializes hidden brand constants at import., The obfuscated module constructs newsletter metadata in mediaAnnotation., Media-message preparation conditionally assigns mediaAnnotation to outgoing media., The package identity differs from embedded defaults identifying itsliaaa/baileys. - **Evidence against:** The preinstall hook only enforces Node.js 20+ and performs no network or file mutation., Reviewed network code is WhatsApp/media functionality; no credential harvesting or shell payload execution was found. ## Public findings ### 1.
